-The X server also has a set of eight numbered @dfn{cut buffers} which can
-store text or other data being moved between applications.  Cut buffers
-are considered obsolete, but Emacs supports them for the sake of X

-This function stores @var{string} into the first cut buffer (cut buffer
-0).  If @var{push} is @code{nil}, only the first cut buffer is changed.
-If @var{push} is non-@code{nil}, that says to move the values down
-through the series of cut buffers, much like the way successive kills in
-Emacs move down the kill ring.  In other words, the previous value of
-the first cut buffer moves into the second cut buffer, and the second to
-the third, and so on through all eight cut buffers.
